Sochi 2014: Nicklas Backstrom & Johannes Duerr test positive

Swedish ice hockey player Nicklas Backstrom became the sixth athlete to test positive at the Winter Olympics.

Austrian cross-country skier Johannes Duerr was revealed on Sunday to have tested positive for blood-boosting drug EPO before the Games.

He had been due to be a seeded starter in Sunday's final cross-country event.

I have absolutely nothing to hide

Backstrom was pulled out of Sweden's ice hockey final against Canada after testing positive for a substance found in an allergy medication.

The 26-year-old, who plays for the Washington Capitals in the National Hockey League in North America, is a star player for his national side, and in his absence Sweden lost 3-0 to Canada in Sunday's final.

"I have absolutely nothing to hide," said Backstrom. "I have allergy problems, and I have been taking Zyrtec-D for many years, and it was a little shocking to me to be honest with you.

"I feel like I haven't done anything differently now than the last seven years. I've been playing internationally for many years and I haven't seen this before.

"I was ready to play probably the biggest game of my career, and two-and-a-half hours before the game I got pulled aside. I was very sad, and honestly I felt bad for the guys.
